In DHS survey, I've noticed one variable named 'hidx/hvidx', which literally expressed as 'Line number of the household member'.
But can anybody explain this in broad?
I mean, what does it mean when 'hidx/hvidx = 1' ?

Normally the household head occupies line number 1 in the household listing, so it seems unlikely that the two variables (HVIDX and HIDX) would have a value of 1 referring to the same person. The DHS variable for the line number of the woman respondent, specified in the IR file, is V003 (also called LINENO in IPUMS-DHS).
